EYEGLASSES.

SPECIFICATION forming partof Letters Patent No. 791,629, dated June 6,1905.

- Application filed JanuaryZO, 1905- Serial No. 241,916.

of St. Paul, in the county of Ramsey, State of Minnesota have inventedcertain new and useful Improvements in Eyeglasses, of which thefollowing is a specification.

My invention relates to improvements in eyeglasses, and particularly toeyeglasses provided with a rigid bridge or nose-piece.

The invention consists generally in eyeglasses having a rigid bridge,lens-clamps pivotally connected thereto with means for normally holdingthelenses in line with each other, and pivoted nose guards or gripsprovided with means for permitting said guards or grips to yieldindependently of any move;

ment of the lens-clamps.

The invention consists, further, in the constructions and combinationshereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification,Figure. 1 is a front elevation of a pair of eyeglasses embodying myinvention. Fig. 2 isa plan view of the same. Fig. 3 is a view similar toFig. 2, but showing the nose-grips separated to a' greater extent. Fig.4 is a view similar to Fig 8, showing the lenses turned outward and thenose-grips also turned upon their pivots by the movement of thelenses.Fig. 5 is a transverse detail section. Fig. 6-is'a horizontal detailsection. of the end of the bridge. Fig. 8 is a perspective view of oneof the nose-grips. Fig. 9 is a perspective view of one of thelensclamps.

In the drawings, 2 2 represent the lenses, which are of any suitable orpreferred form of structure.

3 represents a rigid bridge. Tothe ends of this bridge the lens-clampsare pivotally connected. The-nose guards or grips are also pivoted tothe ends of the bridge, the pivots of the lens-clamps and the pivots ofthe noseguards having, preferably the same center, but said nose-guardsbeing capable of turning on their pivots independently of the movementof the lens-clamps.

Each lens 2 has secured to it a lens-clamp Fig. 7 is a perspective view5, preferably provided with a pivot-post 6,

(see Figs. 5 and 9,) connected to the clamp by the shank 6. These clampsare secured to the lenses by any suitable means, as by the screws 7. Thebridge 3 is provided at each end with a standard 8, having the ears orlugs 9,-in which the pivot-post 6' is mounted. (See Fig. 5.) When thelenses are in line with each other, the shanks 6 engage the standards 8,which form stops for the lens-clamps. A coiled spring 10 is arrangedupon the pivot-post 6 belowits center, one end of this the same timepermitting the lens-clamps to ,be turnedupon their pivots and the lensesto be turned outward. (See Fig. 4.)

The nose-guards consist, preferably, of the clips 11 11 of suitable formto grasp the sides of the nose of the wearer, each of said clips beingformed integrally with or joined to a standard 12, having ears or lugs13: This standard is pivotally united to the pivot-post '6 by the endsof said post extending through openings in the ears 13, and a spring 14:is arranged upon the pivot-post. 6, one end of said springengaging'thestandard 12 and the other engaging the standard 8 on thebridge, Fig. 5. It will be seen that the ends of the pivot-post passfirst through the lugs or ears 13 upon the standard 12 of the nose-guardand then through the ears or lugs 9 upon the standard 8 of the bridge.By this means a pivotal connection is formed between the end of thebridge, the lens-clamp, and the nose-guard. The two parts of thenose-guard preferably extend upon opposite sides of the bridge,(see Fig.1,) and the springs 14 tend to turn the inner ends of said noseguardstoward each other, and thereby to cause said guards to grip the oppositesides of the nose of the wearer with a yielding pressure. When it isdesired to separate the nose-guards for the purpose of putting theeyeglasses in place, the lenses are turned outward, (see Fig. 4,) and ins0 turning the shank of the pivot-post 6 strikes the edge of thestandard 12, thereby causing said nose-guards to turn with thelens-clamps and against the tension of the springs 14:. This separatesthe inner ends of the noseguards and permits the eyeglasses to be placedin position upon the noseof the wearer. The springs 10 bring the lensesinto their normal position in line with each other, while the springs 14press the inner ends of the noseguards against the sides of the nose ofthe wearer. The nose-guards, however, readily adjust themselves to thesize and shape of the nose of the wearer without interfering with theposition of the lenses. In Fig. 3 I have shown the nose-guardsseparated, while the lenses remain in their normal position.

The advantages of this construction are many. I .am able to use therigid nose-piece, which is decidedly advantageous, and the nose-gripsbeing pivoted independently are capable of adjustment to the nose of thewearer without moving the lenses out of line with each other. The lensesare moved outward to open the guards for adjustment to the sides of thenose, and during this movement and after the return of the lensestotheirnormal positions the axes of the lenses are not disturbed.

When it is desired to put the eyeglasses in position, the lenses areturned outward, turning the lens-clamps upon their pivots, and thismovement also causes the nose-guards to be turned out on their pivotsand to be separated a suflioient distance to permit their application tothe sides of the nose of the wearer. When the lenses are released, theirsprings turn the lens-clamps upon their pivots until the lenses are inlinewith each other and in their proper position. Thenose-guards, aetingindependently through the medium of their independent springs andpivots, adjust themselves to the nose of the wearer and press againstthe sides thereof with suflieient pressure to hold the eyeglasses inplace and without interfering with the proper adjustment and alinementof the lenses.

It is obvious that the details of the construetion may be varied in manyparticulars without departing from my invention.

I claim as my invention 1. The combination, with the bridge, of thelens-clamps and the nose-guards independently pivoted to said bridge.

2. The combination, with the bridge, of the lens-clamps and thenose-guards independently pivoted to said bridge, upon common pivots,and independent springs for said clamps and guards.

3. The combination, with the bridge, of the lens-clamps and thenose-guards independently pivoted to said bridge and having commonpivotal centers.

4. The combination, with the bridge, of the lens-clamps pivotallyconnected to said bridge, springs engaging said clamps and tending tohold the lenses in line with each other, the nose-guards independentlypivoted to said bridge, and the springs engaging said noseguards.

5. The combination, with the bridge, of the lens-clamps pivotallyconnected to said bridge, springs engaging said lens-clamps, thenoseguards independently pivoted to said bridge upon the same centerswith said lens-clamps, and springs engaging said nose-guards wherebysaid nose-guards are capable of turning upon their pivots independentlyof the pivotal movement ofthe lens-clamps.

6. The combination, with the bridge provided with the standards 8 havingthe lugs 9, of the lens-clamps 5 provided with the pivotposts 6 engagingsaid lugs, the nose-guards provided with the standards 12 and lugs '13engaging said pivot-posts, the spring 10 upon said posts engaging thestandard 8, and the spring 14 upon said posts engaging the standard 8and the standard 12, substantially as described.

In witness whereof I have hereunto set my hand this 16th day of January,1905.

JOSEPH DAVIDSON LIHVIS.
